Safety Insights for Konkus Marble and Granite
Konkus Marble and Granite operates an establishment with approximately 140 full-time equivalent workers in COLUMBUS, OH, classified under the Table tops, marble, manufacturing industry (NAICS 327991). Across 3 years of mandatory OSHA Injury Tracking Application (ITA) reporting, this employer has accumulated 10 recordable injuries, 1 occupational illnesses, and 0 workplace fatalities. The average Total Case Rate (TCR) of 2.9 injuries per 100 full-time workers per year provides the anchor metric for the C letter grade (Average Safety Record).
Benchmarked against the Bureau of Labor Statistics industry average of 3.3 for Table tops, marble, manufacturing, Konkus Marble and Granite's workforce experiences 86% of the typical injury burden. This ratio matters because TCR already normalizes for hours worked, a 200,000-hour exposure base equals roughly 100 full-time workers, so establishments with very different headcounts can be compared directly. A TCR below the benchmark signals that controls, training, or automation may be outperforming peers.
Multi-year trend analysis is the single most reliable signal here: a one-year spike could reflect a single severe event, whereas sustained elevation across 3 reporting cycles points to systemic hazard exposure. Readers evaluating Konkus Marble and Granite as an employer, contractor, investment, or regulatory target should examine the yearly DART rate (days away, restricted, or transferred), the fatality count of 0, and any year-over-year deterioration shown in the table below. All figures come directly from employer-submitted OSHA Form 300A summaries, there is no modeling, estimation, or third-party adjustment layered on top of the government data.

DART Rate, Transparent Calculation (2024)
DART (Days Away, Restricted, or Transferred) is computed by OSHA as incidents × 200,000 ÷ hours worked. The 200,000-hour denominator equals roughly 100 full-time workers, which lets establishments of very different sizes be compared directly.
2 DART incidents × 200,000 ÷ 250,688 hours worked = 1.60 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
